Jaguar C-X75 Hybrid Supercar development showcased on video

Jaguar showcase the development of the C-X75 hybrid supercar on video After little news on the Jaguar C-X75 – Jaguar’s hybrid supercar – after production plans were cancelled at the end of 2012, this last week has seen a flurry of activity. We’ve had a few select publications given the chance to take a ride – and a brief drive – in the C-X75 at Gaydon, and Jaguar decided to release some new photos of the C-X75 in a fetching shade of blue. We’ve also had the suggestion that Jaguar will give the F-Type a 700bhp version of the C-X75′s hybrid powerplant.

In fact, the 16X so far performs slightly better than Mazda's standard two-liter gasoline engine, said Mitsuo Hitomi, general manager of the Japanese carmaker's powertrain division.
